Abstract
The blood compatibility of polymer is strongly influenced by surface properties of multicomponent polyether polyester block copolymer, such as contact angle, water sorption and microphase separated structure of the copolymer. The X-ray photoelectron spectroscopy test shows that the concentration ratio of oxygen to carbon on the sample-air interface is greater than that in the bulk, suggesting the diffusion of ether-bond towards the air surface. The biggest contact angle, the greatest increasing degree of O/C, and the most tiny microphase separated structure were found in the polyether polyester block copolymer composed of 60%—(PTMGT) and 40%—(PEGT) as soft segment, and this was the best material for blood compatibility.
